A couple went to a sex therapist to try and improve their their sexual body language. They got some good advice about using hand signals to tell each other what was desired in bed. When they got home the husband said, "Okay, when we get into bed and I want sex, I will rub your left breast with my hands. When I don't want sex, I will rub your right breast."
"Well okay, but what about me?" says the wife.
The husband replies, "When you want sex, you can rub my penis once. If you don't want to have sex, just rub my penis about a hundred times."
